09 Jun 2012	Read a binary ZEMAX beam file (ZBF) The function returns the values stored in ZBF file for presentation and analysis in matlab. Author: Chris Betters	This looks cool. Thanks for posting it!
29 Aug 2011	Read ZEMAX Beam File (ZBF) Reads a ZEMAX Beam File into Matlab, allowing presentation of physical optics simulation results. Author: Sean Bryan	Hi Mohamed, I'm actually not sure how Zemax normalizes the ZBF files... For my application, I just wanted a relative map, so the absolute power wasn't what I was after. Let me know if you figure out more about the normalization...sorry I'm not any help. -Sean
02 Aug 2011	Read ZEMAX Beam File (ZBF) Reads a ZEMAX Beam File into Matlab, allowing presentation of physical optics simulation results. Author: Sean Bryan	Weird...maybe GNUMex is broken for Windows 7. Thanks for pointing that out, I'll keep it in mind for the future. Post your native Matlab solution? :) Or does work not allow that...
29 Jul 2011	Read ZEMAX Beam File (ZBF) Reads a ZEMAX Beam File into Matlab, allowing presentation of physical optics simulation results. Author: Sean Bryan	Did installing MinGW and GNUMex work for you? Once those are installed, starting Matlab, changing into the directory where the code is, and typing "mex read_zbf_mex.c" should compile the code. Is that step failing even with MinGW and GNUMex installed?
29 Jul 2011	Read ZEMAX Beam File (ZBF) Reads a ZEMAX Beam File into Matlab, allowing presentation of physical optics simulation results. Author: Sean Bryan	(Oh, I do think it could be rewritten in native Matlab. I was trying to minimally change an existing c-code, so that's why I went with mex.)

05 Jun 2012	Subversion Interface for Matlab Use the Subversion version control system in Matlab Author: Sean Bryan	Mehta, Shalin	On Mac OS X, one needs to search and replace /sw by /usr. Else, works like a charm.

28 Aug 2011	Read ZEMAX Beam File (ZBF) Reads a ZEMAX Beam File into Matlab, allowing presentation of physical optics simulation results. Author: Sean Bryan	Mohamed	Dear Sean Bryan thanks for the file but I found that there is a difference in the power obtained from this file and when zbf is opened in beam file viwer inside Zemax Do you have reason for this

21 Oct 2010	Structure Cut Utility function that applies the same cut to specified elements of a structure.	Sean Bryan	So, that occurred to me too, but then the structure gets passed around a lot. Plus, recursive functions might be as scary as eval, because of the looping potential there. I guess it's just a matter of taste either way. Fee free to write recursive_struct_cut.m and post it too!

21 Oct 2010	Structure Cut Utility function that applies the same cut to specified elements of a structure.	Oleg Komarov	Assuming that you can use recursion infinitely, the concept is that you can call a function and the same function can call itself till it reaches the deepest level. Suppose we have the struct "s" (as created above), then this hypothetical recursive function will apply the cut to the deepest level. function struct = recursiveScut(struct, idx) fnames = fieldnames(struct) if isstruct(sstruct.(fnames{1})) % Jump to the next depth level struct = recursiveScut(sstruct.(fnames{1}),idx) else % Apply cut s.(fnames{1})(...idx...) end end The script above is really just an example.

20 Oct 2010	Structure Cut Utility function that applies the same cut to specified elements of a structure.	Sean Bryan	Is there a way to recursively create a command, and then evaluate whatever you've created? I thought that was what eval was for actually...	Comment only
20 Oct 2010	Structure Cut Utility function that applies the same cut to specified elements of a structure.	Oleg Komarov	There is recursion and eval is not the solution.	Comment only
19 Oct 2010	Structure Cut Utility function that applies the same cut to specified elements of a structure.	Sean Bryan	Right, so the code constructs a string that has that syntax, and "eval" evaluates it. To do this without eval, I would have needed lots of if statements. If the number of dots in the input string is 1, then run the hardcoded s.(sub). If the number of dots is 2, then run hardcoded s.(sub).(subsub), etc. Then if someone put in an input string with more dots than I hardcoded, the code wouldn't work.	Comment only
